AUTOMOBILE HORN.

Application eieaiapril 5, 1era.` seriai'ivo. 287,915.

A further Objectis to lproviee an automa` bile horn of a noveland'eXtremely simple construction, where alll gears, springs, and otherintermediate elements usually found in, such devices betweennthe plungerand the diaphragm are entirely done away with, so that no parts cangetout of order.

llliththese and otherobjects in View7 as will more` fully appear asthedescription proceeds, this invention consists of certain.novelconstructions and arrangements of claimed in the appended claimsReferring to the drawings, Fig. 1 is a side view in elevation, partlysectional, of my improved horn;

Fig. 2 is a rear view in elevation7 partly sectional, through line ,ei-Aof Fig. 1;

Fig. 3 is a detail front view of the vibrator; and

Figs. 1 and 5 are respectively a detail rear view, partly broken away,illustrating the manner of operating my improved horn by means of themotor fly wheel and a detail side view in elevation of the same.`

Referring to Figs. 1 to 3, 10 designates the body of the horn, having aharing' mouth 11 of any suitable shape. The body 10 is interlocking orintegral with flange 12, to which is attached a flanged cap 18 by meansof bolts 111 or in any other suitable manner. Between the fiangc i2 :uidflanged cap 13, a vibrating diaphragm 15 inserted and retained. inposition. The same is preferably made of sheet steel. but can also bemade of mica or libro or any other suitable material. y

A vibrating lever 16, preferably made of sheet metal, is held at one end17 betweeny flange y12 and flanged cap 13 and is connected to the centerofthe diaphragm 1n any suitable manner, for instance, by means of a bolt18. lts freeend 19 is formed so `shown in Fig. 1.

parts, as willbe hereinafter described and g as to provide an edge 2Oabutting "against a toothed portion 2l`provided on the face of a,vibrator 22. f

laidvibrator 22 is fixed or welded on a 60 shaft `23, rotatablymounted,` as shown in Fig. 1. in bea-ring 241,` provided in the rear,yof cap 13 and bearing 25 provided in bracketV i 2G, which is attached`to said fla-nge cap, A

projecting portion 27 of said bracket can be 65 used for` mounting thedevice in position as On the outer end 29 of v shaft 23`is mounted ahandwheel 30 which used to operate thek device. Said hand wheel is made of acomparatively heavy construction so ,thatit acts as a flywheel in such away that one impulse impartedtoitfwithA the. hand willcause the same tomakeseveral revolutions in succession on account of its momentum. TheVposition of shaft 23` can 75 be adjusted at will and thenrendered-per-` manent by tightening screw 31 inset colf lar 32. y n

The operation of the device is veryk simple since all` that is necessaryto `dois to give an impulse to hand wheel 80. The toothed portion'21operatedagainstyedge 20wi11y cause lever 16 to vibrateand therefore toycommunicate its vibrations to diaphragm 1,5.

ln other forms ofhornsthe vibrations yof the diaphragm are usuallyproduced by means of a pinion abutting against an axial pin attached tothe center of the diaphragm; this pin is found to wear out very quicklyand furthermore, there are a number of elementslrequired in order toimpart to said pinion the desired motion.

ln my improved device, the edge of the vibrating lever is madesufficiently long so `that it will not wear out very quickly; fur 95thermore, the form of the lever itself and the way in whiehsame ismounted is Such `the vibrations of the diaphragm are very easilyobtained, the operation of said lever 16 being similar in a way to thatof a vi- 100 brating lever in a phonograph sound'box.

Vibrator 22 is preferably made of embossed sheet metal in order toreduce the cost of production of the device.

The embodiment of my invention as shown in the drawings, on the otherhand, allows various parts to be made small while the hand wheel can `bemade of a comparatively large diameter, thus being easier to operate andhaving greater capacity for acquiring an automobile in such a Way as tocause the same to be operated through the action of a. fly Wheel. Suchan arrangement is illustrated in Figs. 4L and 5, Where itis seen that acrank lever vcomposed of an operating arm 33 and a roller bearing arm34, Whichis mounted on shaft 29. It is obvious that by pulling arm 33 inthe direction of the arrow and causing therefore arm 34: to move to-Ward the right, roller 35, Which is in perinanenty Contact with thesurface of fly Wheel 35, Vwill also come into contact With fly Wheel 36,which is constantly revolving. Therefore, the motion of ily Wheel 36will be transbeing inexpensive to manu lacture and extremely simple inits construction..

It is obvious thatl the various details of construction of my devicemaybe changed to some extent Without departing from the spirit of myinvention; therefore, I reserve :tor myself the right to bring to sameall those changes and modiications which Imay enter fairly into thescope of the appended claims.` 1

I claim: y Y

l.l In a device of the class described and in combination with a bodyand a vibrating diaphragm, a vibrating lever arranged in aplane'substantiallyparallel to said diaphragm, said lever being fixed atone end to said body and having its vibrating portion attached to thecenter of said diaphragm, the

free end of said lever projecting beyond said center.

2. In a device of the class described, the

combination of a body, a vibrating diaphragm, a vibrating lever attachedto the! center oi' said diaphragm and arranged in a plane substantiallyparallel to the same, said lever being fixed to said body at one of itsends and having its other end projecting belever being xed to said bodyiat one of its Aends and having its other end projecting beyond thecenter of said diaphragm and means rotatable in a plane alsosubstantially parallel to said diaphragm controlling the operation ofsaid vibrating lever.

4f. In a device of the class described, the combination of a body, avibrating diaphragm, a vibrating lever attached to the center of saiddiaphragm and arranged in a plane substantially parallel to the same,said lever being xed to said body at one of its ends and having'itsotherend projecting beyond the center of said diaphragm, means rotatable in aplane also substantially parallel to said diaphragm controlling theoperation of said vibrating lever and means for axial adjustment of saidrotatable means.
